Method of cutting shingles or shakes



May 25, 1937, H. B. LOCKHART METHOD OF CUTT I NG SHINGLES OR SHAKES Filed July 15, 1956 r mm m we mL WITNESSES I (W16 r W ATTORNEY-5 Patented May 25, 1937 UNITED STATES PATENT OFFICE METHOD OF CUTTING SHINGLES OR SHAKES 1 Claim.

This invention relates to a method of cutting shingles or shakes.

An object of the invention is to obtain shingles or shakes having an irregular or broken line along their butts or lower edges so that when they are placed on a roof or wall they will present a shadow-like appearance at their butts giving a pleasing appearance and the effect of age. It is understood that only the butts of the shingles are irregular in shape as the top edges of the shingles are straight and set to a straight line as is customary, and while the wall is watertight it has a very different appearance from that of the ordinary appearance.

The invention consists in certain novel steps in the method of cutting the shingles, all of which will be more fully hereinafter described and pointed out in the claim.

In the accompanying drawing- Figure 1 is a view in elevation of a wall or roof having my improved arrangement of cut shingles thereon;

Fig. 2 is a perspective view of a bunch of shingles or shakes, which may be considered to be the first step of my method;

Fig. 3 is a plan view showing sections of the butt ends of the shingles of the bundle cut away, illustrating what may be termed the second step of my method;

Fig. 4 is a perspective view of the bundle of shingles cut away as illustrated in Fig. 3.

Bundles of shingles or shakes as illustrated in Fig. 2 of the drawing are always arranged with alternate layers of shingles l disposed in opposite directions, that is, the butt ends of the shingles are outermost at the ends of the bundles, and what may be termed the tops of the shingles extend inwardly but do not extend the entire width of the bundle. A suitable clamping device, as illustrated at 2, is positioned around the bundle of shingles or shakes securely clamping them together. As illustrated clearly in Fig. 2 of the drawing, these shingles or shakes while of uniform length vary in width.

The first step of the method, therefore, is to form a bundle of shingles or shakes, as shown in Fig. 2 of the drawing, with the butts of the shingles at the ends of the bundle, and then out from the butts of the bundle of shingles sections as shown at 3. It is understood that these sections are cut from the entire bundle and may be of any shape desired so that the butts of the shingles of the bundle because of the variableness in the widths of the shingles will have various shapes or various irregular outlines although, of course, some of the shingles will remain uncut if desired.

Fig. 4 illustrates the bundle of shingles after the butts have been cut, and Fig. 1 illustrates a wall surface or roof on which the cut shingles are secured, it being understood that the top edges of these shingles are in alignment whereas the exposed butts of the shingles take irregular shapes which give an appearance of age and shadow to the surface. The appearance is ornamental and attractive and very distinctive so that with my improved method I am enabled toproduce a shingled surface of novel design and configuration.

While I have illustrated what I believe to be a preferred method of my invention, it is obvious that various slight changes may be made with regard to the form and arrangement of parts without departing from my invention and hence I do not limit myself to the precise details set forth but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the claim.

I'claim:

The herein described method of cutting shingles or shakes, consisting in first forming a bundle of shingles with alternate layers of shingles disposed in opposite directions with the butts of the shingles exposed at both ends of the bundle and said layers of shingles composed of shingles of varying widths and having their side edges abutting, and then cutting from said bundle of shingles sections of the butts of shingles at the ends of the bundle and along planes inclined to the abutting edges of the shingles leaving irregular outlines to the butts of some of the shingles.
